Mitochondrial cyt b genealogy. (A) Haplotype genealogy from Maximum likelihood of cyt b gene tree performed in the software Haploviewer. The model of nucleotide substitution for ML of cyt b gene was K81uf + G (0.047). (B) Geographic distribution of haplotypes present in R. marina from Left Amazon river bank (LAB) and Right Amazon river bank (RAB), and in R. schneideri. The Circle area of each haplotype, coded as a number (Additional file 1), is proportional to its frequency. Asterisks mark haplotypes present in both species. Dots represent inferred unsampled or extinct haplotypes.
